    Oh wow ...

     

    I'm looking to upgrade from an iBook G4 (10.5.8) and trying to decide on 10.6 or 10.7, pro vs. air, and finding this.

     

    Is the battery issue specific to Lion/10.7 on the pro, or is it also seen in 10.7 on the air? How well does the SMC upgrade solve it, how well does the graphic card switch solve it, and what's the current status from Apple on this?

    I had a mid-2007 White Macbook. I had just bought a brand new battery and was getting something like 5 hours of battery. I installed Lion and that went down to 2.5. Meanwhile, the hard drive crashed last week so I bought a brand new MBA 13 base model. Here, I don't have anything to compare to because it came with Lion pre-installed. But with screen brightness all the way down and very little running I'm not really getting the advertised 7. Maybe around 4 at this point.

     

    I called Apple today and they said that there wasn't any known issue with this. I mentioned that there was a thread on Apple Discussions that was viewed by 180,000 people who apparently think it is an issue. He said he would make a case and try to elevate it, but I assume that they're just giving everyone the run around.

     

    With just Safari, coconutBattery says I'm drawing 8.8 watts, which I think is OK.

    I haven't tried the SMC reset or the graphics card thing, but it seems like on here there still isn't agreement as to whether either of these things is helpful.

    @keybounce: Apparently the problem occurs with both of them. My wife has a MBA 11" and she said it runs hot (Not nearly as hot as my MBP was) and she gets only 2-3 hours of battery, and on Snow Leopard she always got between 4-5 hours, and always cool.

     

    @jeremyfromsomerville: I guess a MBA 13" would get something between 5-7 normally, just like a MBP. I ran coconutBattery to compare, and my MBP 13 with screen brightness at half and keyboard brightness at half, running safari (Just this forum open) and dropbox (background) is using only 6.2 watts, and my Battery Estimated Duration is at almost 11 hours. (By the way, I use some plugins with safari: AdBlock, Ghostery and LastPass wich are all active at the moment)

    I'll try to get some info (Battery Duration, Watts consumed) on my wife's MBA tomorrow and then I'll install Snow Leopard on it and check again to see what changes.

    Hi All,

     

    Well the Vendor that sells and supports Apple products for our company came by and swapped the battery out of my new 17" Macbook Pro and this new battery easily gets 5 1/2 + hours while watching videos or surfing web e-mail etc.

     

    The battery they took out,  dead in two hours after running nothing but FINDER.

     

    Thanks,

     

    Joe

    Joe,

    Had you tested the battery prior to the SWAP? DId it test as OK?

    Would be good if a new battery would solve our poor battery life + Lion issue but others have reported installng new battery with no relief of the problem.

     

    If you had not test the battery prior to swapping out  we won't know if possibly your new MBP came with a bad battery?

    However getting over five hours battery life with the new battery is much better than what we are all getting.

    Let us know if you keep getting this amount of time

    Is your MBP running hot? Do the fans reve up frequently and for quite a number of minutes?

    I've noticed (but not quantified) poorer battery performance in Lion (10.7.2) after upgrading from Snow Leopard, similar to the issues many are reporting here.

     

    I think the root of this is in the UI handling of several (if not all) programs, including Safari.

     

    The processes "Safari" and "Safari Web Content" will spike the CPU usage at 35-40% each when scrolling the window. Scrolling in other apps (Mail, Preview, TextEdit) will hit about 25-30% CPU with an additional 15-25% for Windowserver.

     

    Windowserver hits 35% when switching between desktops, 30-40% when going to "command center".

     

    I will test the CPU usage on another machine using Snow Leopard, but I think the transient CPU spikes with such common functions account for the poorer battery performance. I would hate to think that I've sacrificed battery performance and productivity for eye candy!

    Not seeing any of this. Battery still giving me 6 to 7 hours on a Macbook Pro 15" 2007 2.1Ghz with 3 GB of RAM. Yet no difference in battery performance than in Snow Leopard or Leopard (or Tiger for that matter) Obviously a small percentage do heve problems, but millions do not, so whatever I suppose. Love Lion, have forgotten what SL even looked like like so if there is an issue it is only to a miniscule of users. Apple, I am sure will address this in an update if the problem is OS system wide.

     

    Good Luck

    I don't want to sound like a broken record, but both believers and naysayers should take extra effort documenting their Lion battery issues. Simply saying, "My battery lasts only two hours," doesn't cut it.

     

    It's easy to calculate your battery life.

     

    1. Boot your MBP, and set System Preferences so that Displays is at 50%; in Energy Saver, put Computer Sleep and Display Sleep on "never," and turn off all screen savers.

    2. Make sure your machine is 100% charged, but from here on use battery power only.

    3. Open Safari, and leave your MBP on.

    4. Note the time you're starting your test; note the time again when the battery is somewhere around 2-5%. The total test will last somewhere between two and seven hours.

    5. If the results are satisfactory, post them here; if they're unsatisfactory, post them here, too - and contact your Apple Store with the results.

     

    Quantify your results!

  • bellaluna48 Level 1 Level 1 (0 points)

    Setting to display to 50% is unacceptable excuse.  I never did this with my old macbook and still got 7-8 hourse of usage.  (Mainly MS Office - word, ppt, excell, granted I don't like these products better then apple counterparts but none the less it is the environment in which I must do my daily work). 

     

    I with a full charge only recieved 2 hours of battery usage looking at only ppt slides.  Again my only macbook with a battery that had been through it's life cycle 3x according to the mac store still could last 4 hours.  Thus my new MBP is so far a major performance downgrade!

     

    I am returning my computer while I am still in the 14 day window. 

     

    I realize this is not your safar test but I have no interest in browsing the internet for 7 hours on my battery - that is not why I purchaced this computer.  My major issue with the battery is that my old MB with a defective battery outperfomes my brand new MBP. 

  • bellaluna48 Level 1 Level 1 (0 points)

    FYI while typing my responce I went from 28% to 13%

  • Poikkeus Level 4 Level 4 (2,785 points)

    Personally, I set my MBP to 100% brightness. The graphics look better that way, and typography is easier to read. I never use my MBP at 50%. No one's asking you to browse the web at 50%.

     

    However, Apple claims that a current MBP has a battery life of seven hours at 50%. If, based on the procedure I outlined above, your performance is inferior, you should contact your local, friendly Apple Store to state your concerns. At the very least, you'd have hard numbers to use to validate your initial claim - that your current battery life is inferior.

     

    Before you return your unit, it would be cool to share your results so others could profit from the information.

    I have a 2010 17" Core i7 Macbook Pro. I averaged 6-7 real hours of use per charge. This running at 90-100% brightness ( I hate dim displays). This was real usage running Safari and Firefox, consistently, running Photoshop, Maya and Parallels or Fusion, Quicktime player, sporadically. If I spent a lot of time in Photoshop or QT, my time would drop to 4-5 hours. This was througj 10.6.7. I upgraded to 10.6.8 and then Lion, soon after Lion came out. One day, I noticed that my real uptime usage was running about 2-2-1/2 hours. i brought my machine to Apple store and the genius that helped decided my battery was defective and replaced it. The realtime usage did not change. I started researching to see if others were having the same problem, since I had a new battery and discovered several threads, including this one. Since then, I tried every suggestion and nothing worked. I downgraded to 10.6.8 and found that while I can get a battery reading, sometimes, of 7-9 hours (after calibration), I still dont get the realtime usage of 6-7 hours, anymore. Best i can get is 3-4. Some problem was introduced with Lion, maybe even 10.6.8. I am hoping this has not, permanently damaged my battery. There is some smart technology in the battery that is suseptible to virus and I am concerned that I might be corrupted by some bad operating system interaction. Since, Apple is not even willing to, publicly acknowledge there is a problem, how difficult would be for them to say that the problem has damaged the battery. Anyway, I will not go back to Lion until this problem is fixed.

     

    Has anyone tested 10.6.7 to see if it is better than 10.6.8? It was a pain to downgrade from Lion. Is it difficult to downgrade to 10.6.7? What will I lose? Thanks.
